This signature file may be used to cryptographically verify file integrity,
like this::

    $ gpg --keyserver hkp://keyserver.ubuntu.com --recv-keys 0xA16EB94D
    $ gpg --list-keys 0xA16EB94D
      pub   2048R/A16EB94D 2008-08-15 [expires: 2023-08-12]
      uid   Turnkey Linux Release Key <release@turnkeylinux.com>

    $ gpg --verify turnkey-appengine-go-13.0-wheezy-amd64-xen.tar.bz2.sig
      gpg: Signature made Fri Nov  1 08:45:06 UTC 2013 using RSA key ID A16EB94D
      gpg: Good signature from "Turnkey Linux Release Key"

For your convenience we also include file checksums:

    * sha1sum  cae27caa447b532cb7221db25535ec94a8656a94
    * md5sum   7853fbf74e43c23cc1053abd350d53a2

You can calculate these on your end and compare to check for errors, but
cryptographic verification is recommended for security reasons.
